Bamboo

According to Bailey (Stan. Cyclo. Hort.), more than 200 species of bamboo are recognized, varying in size from a few feet to more than 100 in height. The tender, young shoot growth of many of these species is used as food, in the United States mainly in Chinese dishes. Sprouts harvested in the United States are limited to Hawaii and Puerto Rico, but substantial quantities are imported. Since new sprout growth quickly becomes hard and woody, the maximum period of exposure of edible parts to direct pesticide application would be approximately
a month.
